SHOVEL ATTACHMENT.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed April 27, 1906. Serial No. 314,082.

To all whom, it may concern:

Be it known that 1, Firms CLARK, a citizen of the United States,residing at Midland, in the county of Greene and State of Indiana,

have invented certain new and useful Im.

provements in Shovel Attachments, of which the following is aspecification.

The present invention is in the nature of a fulcrum attachment forshovels, which is especially designed for the use of miners'and which isso constructed as to have a spring action which facilitates the raisingof the material being operated upon into a car or other elevatedposition.

The object of the invention is to provide a fulcrum attachment of thischaracter which can be readily attached to any spade and which isexceptionally strong and durable in construction.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the followingdescription, and accompanying drawings, in which Figure 1 is aperspective view of a shovel provided with the fulcrum attachment. Fig.2 is an enlarged perspective view of the spring member constituting theattachment. Fig. 3 is a similar view of the clamp employed to secure theattachment to the shovel, and Fig. 4 is a longitudinal sectional viewthrough the shovel.

Corresponding and like parts are referred to in the followingdescription and indicated mall the views of the drawings by the samereference characters.

The invention is shown as applied to a shovel of the conventional type,in which the numeral 1 designates the blade, and 2 the handle. Theattachment is in the form .of a spring member which is preferably formedof fiat material and which comprises two arms arranged at angles to eachother. The shorter arm 3 fits against the lower portion of the handle 2and is provided at its extremity with outwardlyextending flanges 4,which embrace the handle and enable a rigid joint to be formed betweenthe two members. The opposite arm 5 extends rearwardly from the blade ofthe shovel and has its extremity bent upwardly, as seen at 6. Thisrearwardly-extending arm 5 normally.

bears against the surface'of the ground and tends to hold the shovel inthe desired position for pushing forward under the coal or similarmaterial. The clamping member employed for connecting the shorter arm 8of the attachment to the shovel is in the form of a U-bolt 7, which fitsaround the handle 2 at a point adjacent the blade 1 and cooperates witha bar 8, which bears against the short arm of the attachment and isprovided with openings through which the two members of the U bolt 7 arepassed. WVith this construction it will be apparent that the springmember can be readily attached or removed from any of the types ofshovels in common use. i

In the operation of the device the shovel is pushed forward under thecoal and the latter raised by hearing down upon the handle 2 in such amanner as to cause the longer arm 5 of the attachment to serve as afulcrum. This has the result of compressing the spring member, and theupward force exerted by the spring is utilized in throwing the coal inthe car or other rceptacle. Owing to the fact that the attachment isformed of flat spring material, it is adapted to slide readily over thesurface of the ground and forms a guideway for directing the movementsof the blade. The upwardly-bent extremity of the long arm 5 prevents theend of the attach ment from digging into the ground and also forms ashoe, which bears against the surface of the ground when the blade 1 isbeing lifted.

Having thus described the invention, what is claimed as new is- 1. Thecombination of a shovel or like implement comprising a blade and ahandle, a fulcrum attachment comprising two arms ar ranged at angles toeach other, one of the arms extending rearwardly from the blade andhaving a spring action, while the opposite arm fits against the handleand is provided toward one end with a pair of outwardly-extendingflanges which embrace the same, and a clamping member spaced from theflanges and serving to secure the lattermentioned arm to the handle.

2. The combination of a shovel comprising a blade and a handle, afulcrum attachment comprising two arms formed of flat material andarranged at angles to each other,

one of the spring-armsextending rearwardly l ter-mentioned arm of theattachment in orfrom the blade and having its extremity der'to hold thesame rigidly in position. 10 bent upwardly, the said arm having a In.testimony whereof I affix my signature spring action, While the oppositespring-arm in presence of two Witnesses.
